YARN-sume. MACHINE.

To all whom it may concern:

Be it known that I, CHARLES E. (JLARK, a citizen of the United States,residing at Durham', in the county of Durham and State ofNorth'Carolina, have invented new and useful Improvements inYarn-Sizingl Machines, of which the followingis a speciication.

This invention relates to improvements in machines for slashing orsizing warp yarns or threads prior to the use of the same in a loom, theobjectof the invention being provide means to enable the machine to bestopped at any time prior to the filling of the loom beam with sizedyarn without causing the sizing or starch on those portions of the yarnsbetween the sizing roller and the drying cylinder of the machine toharden and render it necessary to cut out such portions oit the yarn;and the said invention consists in the construction, .combination andarrangement of devices hereinafter described and claimed.

In the accompanying drawings z-Figure 1 isa side elevation of a yarnsizing or slashing machine provided with my iniprovements. Fig. 2 is anelevation ot' the front end of the same. F ig. is a detail sideelevation of the front end of the same. Fig. 4 yis a detail elevationot' the slack take up mechanism fory raising the sizing or slashing rolland causing the arm engaging in the immediate vicinity of such roll tobe run between the `squeeze rollers when the machine is stopped so as toprevent the sizing from hardening on the yarn and rendering it unfit foruse in the loom. Fig. 5.1s a vertical sectional view of the same. Fig. 6is a vertical transverse. section through the sizin tank, showing themode et' mounting the sizing roller therein.

` The frame of the sizing or slashing machine is indicated at l. Thesaid machine, as is usual, is provided at its rear end with the usualkettle ortank 2 which contains the starch or sizing material( Above thesaid tank and having their bearings'ln'thesides of the frame 1 are thelower squeeze' rollers 3. The upper squeeze rollers 4l which are adaptedto bear on the upper sides of and coact with the lower squeeze rollersare normally, during the operation of the machine mounted in bearings 5on tlie'sides of the said frame 1, said bearings opening up-` wardly soas to permit the upperI squeeze rollers to be unshipped therefrom. Inac- Specicaton of Letters Patent.

cordance with m invention, I provide the frame of the mac line withbearings 6 which extend upwardly to a higher point lthan the bearings 5and which are adapted to receive the journals of the upper squeezerollers 4` when the latter have been unshipped fromV their bearings 5,the said bearings 6 enabling the said upper squeeze rollers to bemounted at such an elevation that they will not enf gage the lowersqueeze rollers 3. A slashing or sizing roller 7 has its journalsmounted in vertical grooves 8 in the sides of the tank so that the saidroller 7 is rendered capable of vertical movement, said roller whenlowered, operating to cause the yarns to be sized or run through thestarch or sizing. material in the tank 2, and when raised permitting theyarns to be run without coming in contact with the starch of the sizingmaterial. A direction roller 9 is mounted on the rear end of the frame1.

The usual drying cylinder 10 has its bearings as at 11 on the sides ofthe frame 1 and at a suitable distance from the front end thereof.Somewhat in rear of the drying cylinder 10 is a smaller drying cylinder12, the bearings of which are indicated at 13. A lower direction roller14 ismounted in the sides of the frame, 1 at a point below the frontside ot the drying cylinder 10 and an upper direction roller 15 ismounted at a higher point in the sides of the frame 1 and slightly inadvance of-the lower direction roller 14. A roller 16 has its bearingsnear the front end of the frame 1. A roller 17 of less diameter than theroller 16 is mounted near the latter, the bearings being indicated at`18 somewhat in advance of those of the roller 16. A tension or frictionroller 19 -has vertical slotted bearings 20 011 the sides of the frame 1near the front end thereof, the journals 21 of roller 19 operating insaid slotted bearings and the latter enabling said roller 19 to beraised and lowered. Said roller when lowered bears onthe roller 16. Theusual bearings 22 are provided at the front end of frame 1 for the loombeam 23 or that beam on which the warp yarns are wound that have beensized by the machine. In connection with the vertically movable frictionor tension roller 19, I provide a lever 24 which is fulcrumed on theframe 1 as at 25 and is provided with a bent arm 26 which bears underthe spindle or journal of said roller. When the lever is in the positionshown in full lines in Fig. 3, the roller ios 19 bears on the roller 16but by lowering that end of the lever provided with a handle 27 the arm2f: of the lever will run under the spindle of said roller 19 and raiseand 5 support the latter at a point above the roller 16 as indicated indotted lines in Fig. 3.

A section of beams 2S 29e-30 are shown in Fig. 1 mounted, as usual, on aframe 31, spaced from the rear end of the frame 1 and in line therewith.The yarns, indicated at a, from the beams A28h29-30, pass for.- wardlyover the roller 9, then downwardly under the vertically movable sizingon slashing roller 7 then upwardly and forwardly over -the lower squeezerollers 3 and under the upper squeeze rollers 4, then forwardly andupwardly to the drying cylinder 10, then around the under side of saidcylinder, rear` wai'dly and over the rear side of the cylinder 12, thenforwardly and under the roller 14, then upwardly over roller 15forwardly over' the roller 1 9, then between said i'oller and the roller16, under said roller 16, over the roller 17 and to the loom beam 23 orthat beam on which the sized yarns are wound. l When the said beam isfull, vit isreinoved from the frame 1 and taken to the drawing* in roomfor drawing in into the harness for the loom. In accordance with myinvention, I provide a take up mechanism for the yarns which I will nowdescribe. y

A pair of vertically disposed standards 32 are secured to opposite sidesof the frame 1 at a point between the sizing tank and the cylinder 12.Each of the said standards has at its upper vend a rearwardly anddownwardly curved arm 33 and is provided on its inner side with Iagroove 34 which extends from'the lower to the upper end of the standardand terminates vin a downwardly i and rearwardly curved portion 35 inthe standard arm 33. A pair of rollers 36-37 are mounted respectively inbearings 38-39 ards, the roller 37 vbeing somewhat higher than theroller 36. The warp threads pass over the rollers 36-37. I also providea roller 40, the journals of which engage the grooves 34. vSaid rolleris normally mounted above the rollers 36-37 and inthe downturned end ofthe curved upper portions 35 of the groovesu34 so that under normalconditions, when the machine is in operation, the roller 40 is above andentirely out of engagement with the warp threads.

vThe operation in sizing or slashing the warp threads is as follows-Thecylinders 10-12 and the rollers 23 being in revolution in thedirectionsindicated by the arrows in' Fig. l, the warp threads are drawn from thebeams 28-29-30 and wound on the beam 23 and, hence, are caused to travelunder the sizing roller 7 in contact with the sizing ma on the rear andfront sides of the said stand? between the upper and lower squeezerollers 3--4- which serve to remove superfiuous siz ing material orstarch from the yarns, the

sized yarns being dried as they pass over'the cylinder 10and,hence,being delivered to the beam 23 in a dry and Finished conditionsuitable for use in the loom. Ileretofore, so far as I amaware,iiiinachines of this class iu the event'that the machine isstopped before the beam 23 is full, even for a very short space of time,the yarn. in the act of sizing andv which has not passed through thesqueeze rollers become hardened and injured by the dryinQ of the sizing`material thereon and rendered unfitfor use inthe loom and, hence, beforethe machine could be again started all of the yarn between the sizingroller 7 and the beam 23 has to becut out and removed, causing the totalloss of such lengths of yarn and also causing a great loss of time onthe part of the attendant. My invention enables the machine to bestopped without injury to the yarns and without the necessity of cuttingout the yarns. In the operation of the nia-- chine as provided withmyimprovements, when the machine is stopped at any time -prior to -thefilling of the beam 23, the attendant unships the roller 40 from itselevated bearings in the curved portions 35 of the grooves 34 andpermits the journals of said roller to pass downwardly in the'verticalportions of s aid grooves 34, thus causing the said roller 40 to engage.the yarns between the rollers 36-37 and in so doing make a bight in theyarns, as indicated in dotted lines in Fig. 5. The said roller 40 beingheavier than the sizing roller 7 in thus making the bight in the yarntakes up the slack in the yarns between the squeeze rollers and theroller 9 and, hence, causes the yarns to raise the sizing roller 7 outof the sizing tank and those portions of the yarnto which4 Vsize hasbeen applied and which had not .been reached by thefsqueeze rollers willbe yarns are entirely removed from contact with the lower squeezerollers and he also by means'of the lever 24 in the manner hereinbeforedescribed raises the roller 19 from the ioller 16 thus relieving thetension of said rollers on the yarn. He then turns the beam 28 backwardso as to cause the yarns between such rollers and the roller 19 to berewound on said beams 28-29-30 and all danger of hardening and injuringthereof is obviated.

Having thus described the invention,what is claimed, is

ln a sizing machine of the class described, the combination of a sizingtank, a sizing roller movable vertically in the tank, a drying roll,squeeze rolls disposed in the line of 'feed ot' the threads between saidsizing roller and the drying roll, grooved guide standards arranged inthe line of feed of the threads between the squeeze rolls and dryingroll and having ol'fset supporting portions at their upper ends,transverse guide rolls journaled upon the guide standards on oppositesides of the guide grooves therein and below said otfset supportingportions, and a weighted tension element normally held by saidsupporting portions above and out of Contact with the threads andadapted when released lto travel in the guide grooves and engage andcarry the threads downwardly between and below the guide rolls, wherebyto form a bght or loop in the yarns and tension the same to raise thesizing roller and cause the yarns to pass between the squeeze rolls.

In testimony whereof I alix my signature in presence of two witnesses.
